If the tube has a hole on the outside of the wheel, toward the casing, a common cause is a sharp object, such as a shard of glass or piece of wire, that first drilled through the casing and caused the hole in the tube. The sharp object usually falls off again and can no longer be seen later.
For me, putting on puncture protection tires, which are tires with an extra protective layer underneath the tread, worked wonders and permanently solved the problem.
It is possible that the rim tape on the rim has slipped sideways or is no longer intact. The rim tape covers the rim holes under which the wheel spoke fasteners are located. In this case, I would renew the rim tape. The best experience I have made with a self-adhesive rim tape, because it cannot slip so easily.
Basically any tube listed here can be used. Since the tubes are expandable, they are suitable for several tire widths and some tire diameters. Regarding valves, see next question.
The automotive valve is often abbreviated as AV valve. Equivalent terms are car valve, Schrader valve, MTB valve and American valve.
The Dunlop valve, or DV valve for short, is also known as Woods valve and English valve.
The Sclaverand valve, or SV valve for short, is also called French valve and Presta bike valve.
For more info, see the blog article on bike valves.
The important thing is that the tube has the right size. Otherwise, it does not matter.
